In this study of 54 cases wrapped with muslin over the last six years, two cases of optochiasmal arachnoiditis occurred. Three patients had early rebleeding(More)
Ossification of the ligamenta flava (OLF) and posterior longitudinal ligament (OPLL) of the spine causing spinal cord compression is described mainly in Japanese patients and is often termed as 'Japanese disease'. We are reporting a case of OLF of the thoracic spine seen in a male Caucasian who presented with an intractable intercostal pain. This is the(More)
The optimal control problem for the viscoelastic melt spinning process has not been reported yet in the literature. In this study, an optimal control problem for a mathematical model of a viscoelastic melt spinning process is considered. Maxwell-Oldroyd model is used to describe the rheology of the polymeric material, the fiber is made of. The extrusion(More)
